Nightwing/Funny

From Nightwing: Year One we have this exchange between Dick and Commissioner Gordon when the former is introducing himself as Nightwing.

Gordon: Say something... Say something only the The Kid would know.
Nightwing: My former associate has a thing for bats? You took up a pipe to quit smoking cigarettes? Wait, howzabout-- HOLY MISTAKEN IDENTITY!

Gordon: *lowers his gun*
